Fair warning: This is a bug, and at some point we'll fix it. If you want the Pinkie Pie avatar to actually keep, you'll want to buy it from the store (which also contributes to charity).
I didn't realize the pony was for sale at the time of this post. I'm not trying to encourage people to rob wotc. I will delete.
That's awesome! Thanks for being a good human.
